    -----------------------------

    Show a comparison between the old and new versions of a file from changes
    made on a particular revision.

    This is similar to the ``diff`` handler. However, this form features
    a split or side-by-side diff rather than a unified diff.

    The ``context`` query string argument can be used to control the lines of
    context in the diff.

    The ``filecomparison`` template is rendered.
